DESCRIPTION
2.1 INTRODUCTION
Your new Sullair flood-lubricated rotary screw air
compressor will provide you with improved reliability
and greatly reduced maintenance.
Compared to other types of compressors, the Sullair
rotary screw is unique in mechanical reliability, with
"no wear" and "no inspection" required of the working
parts within the compressor unit.
Read Section 6: Maintenance to keep your
compressor in top operating condition. Should any
questions arise which cannot be answered in the
following text, call your nearest Sullair office or the
Sullair Corporation Service Department.
2.2 DESCRIPTION OF
COMPONENTS
Refer to Figure 2-1 . The components and
assemblies of the ES-6 Series air compressor are
clearly shown. The complete compressor consists of
an encapsulated compressor system, inlet system,
cooling system and control system.
The compact design of the ES-6 Series air
compressor provides easy access to all serviceable
components.
2.3 ENCAPSULATED
COMPRESSOR SYSTEM,
FUNCTIONAL DESCRIPTION
Refer to Figure 2-2 . The encapsulated compressor
includes compressor unit, fluid management system,
and motor section. The Sullair compressor unit is a
single-stage positive displacement lubricated type
compressor. This unit is equipped with tapered roller
bearings on the discharge, and cylindrical roller
bearings on the inlet end for high load carrying
capacity. This unit provides continuous pulse-free air
compression to meet your needs. With a Sullair
compressor there will be no maintenance or internal
inspection of the compressor
.
Fluid is injected into the compressor unit in large
quantities and mixes directly with the air as the rotors
turn, compressing the air. The fluid flow has three
main functions:
1. As coolant, it controls the rise of air tempera-
ture normally associated with the heat of
compression.
2. It seals the leakage paths between the rotors
and the stator and also between the rotors
themselves.
3. It acts as a lubricating film between the
rotors allowing one rotor to directly drive the
other, which is an idler.
The air/fluid mixture discharges directly into the fluid
management system.
The fluid cooler bypass valve helps assure proper
cooling by directing the fluid to the fluid cooler when
discharge temperature reaches the thermostat
temperature setting.
During start-up in cool ambient conditions, the cooler
pressure drop will cause the filter bypass valve to
open up, assuring adequate fluid supply to the
compressor.
All fluid entering the compressor unit passes through
WARNING
DO NOT remove caps, plugs and/or other
components when compressor is running
or pressurized. Stop compressor and
relieve all internal pressure before doing so.
